Turning sensory inputs of all kinds into defined electrical signals that can be interpreted and acted upon by both stationary and portable medical equipment as well as implants, sensors find many applications monitoring blood pressure, heart rates, glucose levels and many other parameters by which human health can be evaluated.

Based on ethnographic research in makerspaces and co-working spaces in Nairobi, Alev Coban argues that postcolonial technology entrepreneurship is neoliberal and inherently political work. Technology developers, narratives, prototypes, and digital fabrication tools unite to achieve ambiguous Kenyan futures of technocapitalist market integration and decolonial emancipation in order to foster national well-being and disentangle Kenya from exploitative global structures. 410 0$aSozial- und Kulturgeographie Series 606 $aSOCIAL SCIENCE / Human Geography$2bisacsh 610 $aAfrica. 610 $aCapitalism. 610 $aGeography. 610 $aMakerspace. 610 $aPostcolonialism. 610 $aSocial Geography. 610 $aSociology of Technology. 610 $aSpace. 610 $aTechnology. 610 $aWork. 615 7$aSOCIAL SCIENCE / Human Geography. 700 $aCoban$b Alev$4aut$4http://id.loc.gov/vocabulary/relators/aut$01740702 801 0$bDE-B1597 801 1$bDE-B1597 906 $aBOOK 912 $a9910861956203321 996 $aPerforming Technocapitalism$94166499 997 $aUNINA
